Snyder et al. show that distinct populations of phagocytic cells in cauliflower corals (Pocillopora damicornis) and starlet sea anemones (Nematostella vectensis) engulf bacteria, fungal antigens, and beads. The image shows a cauliflower coral cell challenged with Staphylococcus aureus. Yellow arrow shows an internalized, pH-activated Staphylococcus aureus particle that fluoresces bright green at a low pH. White arrows indicate the cocci bacterial particles. Staphylococcus aureus particles are fluorescent after the fusion of the bacteria with the lysolitic vesicle, which leads to lowered pH. Scale bar - 10 μm.
